The Atlas of the Amazon is the best comprehensive view of the many different natural and social aspects that emcompass the Amazon river basin. It does a thorough job of describing the natural environment and the differences between sub-regions.

Unfortunately, the entire Amazon is altogether too large and too diverse for a single volume such as this one, but I believe that it does reasonably well at condensing some of the main aspects and choosing specific themes to focus on. For example, the book focuses on the geology of the reason, explaining the differences in river color by showing the different origins of the rivers (there are yellow, black, green, and transparent waters). Additionally, the book singled out the lifecyle of local catfish, that crisscross the region by their feeding and breeding habits.

One of the outstanding qualities of this book is the images, which try to do justice to the beauty of the region. Through the pictures, one can tell the deep differences between the sub-regions; some are mountainous, some are planes, some are swamps, in some places the forest is denser, etc.

If you are planning a visit to the Amazon, or have a strong interest in the Amazonian ecosystem, this may be the best book available today. I strongly recommend it.
